EYEGLASSES.

To all whom it may concern:

cation.

ticularly directed to and applicable to what are known as finger-pieceor finger-lever mountings.

This invention aims to overcome many of the serious objections anddefects found to exist in eyeglasses in general use, and among theobjects of the invention 'arethe provision of a mounting which will beof attractive and ornamental appearance; which will permit of ready appication and removal of parts for :purposes of repairg which will allowof instant adjustment of the springs to suit the convenience ofthe=wearer; and

which adjustment or regulation may be madeby any person skilled in theart; which will be of the simplest, cheapest and most durableconstructiom'which will positively retain the eyeglasses in positionunder all conditions and which generally will meet all the requirementsof the public and prove highly eflicient and practical from every pointof View.

' With these objects in view, my invention *eolisists of an eyeglassembodying novel features of construction and combination of parts, substantiall r as disclosed herein.

In order=that t e details of construction and the operation of my 'imrovements may be fully 'understoodand t e many advantageswhichresultfrom my invention may be' fully appreciated, I have illustrated inthe 'accompanyingdrawings eyeglasses constructed in accordance with andembodying my invention, and to which I invite attention.

'Beferring to the drawings, in which similar numerals of referencedenote corresponding parts in all the views of the drawlhe numeral 1designates the lenses to which are secured by suitable fastenings theears 2 formed with the straps 8, resting snugly against the edges of thelenses, and the straps are connected by the nose bow or bridge 4, formedadjacent the straps with the horizontally disposed flat ortions orplatforms 5, each platform being formed with a raised projection forminga bearing or pivot 5' for pivotally supporting thenose grip supportinglevers as will hereinafter be described. Threaded openings 6 areprovidedwhich extend through the saidpro- Leections, the purpose of whichopenings will .pointed' out later on. Thediameterbf the lower portion ofeach ofthe-projections in the form of construction shown in Figs. l

Theselovers are piv oted upon the lower larger portions of these projections,as is clearl shown in 1* ig. 4 of the drawing. The springs 21 areprovided at their inner ends with depending projections 20 which aresecured in slots or openao ings 26 in the, said washers .12. Thesesprings are coiled as indicated in Figs 6 of the drawing and their;outer. ends-are'provided with depending projections23 which arendaptedtocontact with the rearward extending portions 16 of the nose gripsupporting levers, as indicated at In the construction shown-in Figs. 7 and8, the washer-12 is identical with the same part shown in the precedingfigures of the 40 drawing and is provided with a similar central,hexagonal opening 12".

the nose grip supof the springs upon optioian or mechanic;

From the foregoing description, taken in connection with the draw ngs,the operation of my improvements will'be readily understood, and. itwill be evident that the tension the inner ends of the finger leverspresses the pads against the nose to retain the eyeglasses in properposi' tion, andto apply or remove the eyeglasses, it is only necessaryto apply pressure to the finger pieces or graspingportions of saidlevers to move the levers and release the pads.

It will also be observed that the heads of the screws entirely cover andprotect the springs and preventcontact with the springs or the entranceof dirt or foreign matter.

It wilt-also be apparent that the tension of the springs may beregulatedor adjusted by. turning the disks or washers to change thecoils of the springs, and that such adjustment may be accomplishedinstantly by any person skilled in the art.

It will also be evident that in the event of breakage of the spring thata new one may be supplied at a very small cost and be quickly placed inposition.

It will also be noted that the improvements will cause the eyeglasses tofit the nose of the wearer perfectly, but at the same time willnotbecome dislodged by striking by a puff of' wind or by perspirationupon the nose. i

Also any improvements may be used in connection with'eyeglass mountingsof the lever type which employ round coil springs in general use,,andthus add greatly to'the efliciency of such glasses.

In general, it will be seen that my improvements are designed to meetthe requirementsof the trade and public, and that they produceeyeglasses of ornamental and attractive appearance which can be producedat the proper price; which possess the neces- Sary strength anddurability; which will fit the nose comfortably and securely; avhichpermit of adjustment or regulation of the tension of the springs; which'can be easily and quickly repaired or adjusted; .whichprotectzthe-springs; against undue wear and the entrance 02E dirt orforeign matter;

,whi-ch will permit of the removal or a'p lication of parts whennecessary by anys 'lled and which inwwery particular will prove entirelyeflicient and practical. I
